What defines this ZIP
Metrics where this ZIP sits in the tails of the national distribution — the ones that most set it apart. Select any tile for its definition and methodology.
Industrial-pollution burden
in the top 0.7% nationally
Lower is healthier
ST99thUS99thDefinition & source ›
The EPA’s modeled screening score for industrial chemical releases, weighting the amounts released by their toxicity and how many people live nearby — a relative comparison score, not a measured exposure.
Full methodology ›Arsenic in groundwater
22.4%
in the top 5.4% nationally
Lower is healthier
ST77thUS95thDefinition & source ›
The modeled probability that untreated groundwater in this area — the source private wells draw on — exceeds the federal arsenic limit of 10 micrograms per liter.
A modeled likelihood for untreated groundwater, the source drawn on by private wells, which are federally unregulated. It is not a measurement of treated water delivered by a public system, and it is not a test of any individual well.
Full methodology ›Grocery access
0.2 per 1,000 residents
in the top 7.3% nationally
Higher is healthier
ST89thUS93rdDefinition & source ›
The number of full supermarkets inside this ZIP’s boundary, per 1,000 residents.
Counted from establishments located inside this ZIP’s boundary, so one just across the line is not counted. Where a ZIP has too few residents for the density to be reliable, no value is published rather than an unreliable one. ZipVitals’s food-access signal is derived from these in-ZIP densities — it is not USDA’s food-desert designation, which measures distance to the nearest supermarket. Where a leg is missing, a ZIP reads “not determinable,” never “not a food desert.”
Full methodology ›Mammography
81.3%
in the top 5.8% nationally
Higher is healthier
ST79thUS94thDefinition & source ›
The estimated share of women aged 50–74 who had a mammogram within the past two years.
Full methodology ›Loud transportation noise
1.3%
in the top 14.8% nationally
Lower is healthier
ST97thUS85thDefinition & source ›
The modeled share of residents exposed to average road, rail, and aviation noise at or above 65 decibels — around the volume of normal conversation.
Full methodology ›Radon
2.5 pCi/L
in the top 21% nationally
Lower is healthier
ST94thUS79thDefinition & source ›
The modeled typical indoor radon level for this area, in picocuries per liter — the EPA recommends fixing a home at 4 pCi/L or above.
Modeled from indoor-radon measurements. In Alaska and Hawaii, where those measurements are not published, a US Geological Survey geologic radon-potential category stands in — a coarser input, disclosed rather than hidden.
Full methodology ›Median household income
$105,156
in the top 16% nationally
Higher is healthier
ST92ndUS84thDefinition & source ›
The middle household income in this ZIP — half of households earn more, half earn less — in dollars per year.
Full methodology ›Fine-particle (PM2.5) exceedance
0.27%
in the top 23% nationally
Lower is healthier
ST99thUS77thDefinition & source ›
The share of days in the year when modeled fine-particle (PM2.5) pollution was above the EPA’s daily limit of 35 micrograms per cubic meter.
Full methodology ›Humid extreme heat
26.3 days/year
in the bottom 24% nationally
Lower is healthier
ST93rdUS24thDefinition & source ›
The average number of days per year when modeled heat stress — temperature, humidity, sun, and wind combined — reaches levels hard on the body outdoors.
Full methodology ›Dry extreme heat
0.3 days/year
in the bottom 27% nationally
Lower is healthier
ST99thUS27thDefinition & source ›
The average number of days per year with a modeled daily high of at least 95 °F.
Full methodology ›The read
Overall, North Berwick, Maine (ZIP 03906) places in the top 38% healthiest ZIPs nationally (12,300th) and the top 32% of Maine (129th).
The measures land in both directions, and neither dominates: grocery stands in the top 7.3% nationally, and modeled mammography registers in the top 5.8% nationally. Modeled food insecurity settles in the bottom 11.0% nationally, and tree cover sits in the top 11.9% nationally. Distance to a nursing home lies at the national minimum, shared with about 27% of ZIPs. Modeled short sleep rests in the bottom 14.0% nationally. Pulling the other way, modeled industrial-pollution burden resides in the top 0.7% nationally, and arsenic is in the top 5.4% nationally. Fiber broadband lands at the national minimum, shared with about 19% of ZIPs. Modeled loud transportation noise stands in the top 14.8% nationally.
Beside the areas that surround it, industrial-pollution burden runs far higher than the surrounding ZIPs on this measure. For readers new to these terms, industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. Arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. Loud transportation noise is the modeled share of an area exposed to road, rail, and air noise at or above 65 decibels, near conversation volume. Among nearby ZIPs, the nearest healthier one overall is ZIP 03901, just across the boundary.

How these were chosen: only ZIPs with a published Score appear — a nearby ZIP with too little data to score won’t. Nearby means closest by distance between ZIP boundaries, which can cross state lines. A similar health profile is a close match across the nine Score domains, not similar demographics. Distances are measured between ZIP boundaries — ZIPs that touch share a border. How distance is measured

About the ± — it’s this estimate’s give-or-take (statisticians call it the standard error). The true life expectancy for this ZIP most likely falls within 3.85 years of 76.2, and it’s very unlikely to be off by more than twice that.

How these lists were built: they draw only from ZIPs that have a published Score, so ZIPs with too little data to score are not listed. Distance-based lists use distance between ZIP boundaries with no state filter, so an out-of-state ZIP can appear. Statistically similar means a close match across the nine Score domains, not a demographic match: the measure is the cosine similarity between two ZIPs’ domain scores, taken over the domains both ZIPs have data for and only where that overlap covers at least six of the nine — and where no ZIP clears that minimum-overlap floor, that list is left out rather than filled with a weak match. How distance is measured
